Is My Alternator Faulty?

Is My Alternator Faulty?

What Is An Alternator?

Alternators are commonly used in ‘newer’ vehicles. Their function is to charge the battery and get power to the electrical system when your engine is turned on.
The alternator earns its name from the term ‘alternating current’ or AC.
Nearly all alternators are seated using brackets which bolt on to a specific point on the engine.

Is My Alternator Faulty?

You may be experiencing slow start ups, flickering headlights or a warning light on your instrument panel, but is it the alternator?

Milner’s have put together a quick test to help you out.

The Multimeter test.

For this test you will need a multi-meter / multi-tester / voltmeter. These can be purchased online or at your local motor factors, you may even have change left from a tenner.
With the engine switched off, connect the meter to the battery terminals RED positive & BLACK negative. (Do not connect these to the cable clamps)

The meter should read a minimum of 12.3 volts or if you have a good condition battery, it should read at least 12.6 volts.
If your meter is showing below this reading it could be a result of one of the following reasons:

  • The battery is discharged. (Recharge your battery)
  • The battery is low on distilled water. (The water should be 5mm above the plates. DO NOT fill the battery full to the top).
  • The battery has a high internal resistance. (Sulphide plates)

Multi-meter test

IF your battery is in good condition.

Start your engine and rev to 2000 RPM. This will draw power on the battery and cause the voltage regulator to start the alternator working. Let the engine idle and the reading should be:

  • A minimum of 13 volts.
  • Revving the engine will fluctuate the voltage between 13 to 14.5 volts, which indicates the alternator is in good shape.
  • If the voltage when revving the engine stays the same or decreases, then your alternator is more than likely faulty.
  • To test the regulator, repeat the process with the lights, radio and A/C (if fitted) switched ON.
    Rev the engine again to a constant 2000 RPM. The meter reading should read above 13 volts and no more than 14.8 volts. IF the meter reads above 14.8 volts, the alternator is probably over-charging.

If you are unsure on the above, take your vehicle to your local garage and get them to do the test for you.

 

(The above information is a guide only. It is down to the operator to gain the correct voltage tolerances for the vehicle on test. The above tests are for a standard 12 volt negative earth system. A good working battery will show 12.6 volts and a minimum of 12.3 volts.)

Nissan Navara Sagging Rear Suspension Issues.

Nissan Navara Rear Suspension Issues

 

Nissan Navara Rear Suspension Issues.

The model in question is the Navara NP300 2015 onward.

The vehicle itself gets a 4.5 out of 5 stars by AutoExpress, reporting  ”Small bumps are ironed out far more effectively and the floating feeling over sudden undulations is much better suppressed.”
However, while it brings some benefits when unladen, it has been criticised for struggling to cope with anything approaching its claimed load weight of 1 tonne. Further more Nissan state the NP300 has a 3.5 tonne towing capacity.

Despite the claimed stats, opinions from owners are coming in that their Nissan’s are ”struggling” with loads well under the claimed payload. Unmanageable steering and sagging springs are just a few to mention.
Vehicles that are used for work or tow large trailers are proving that the standard rear suspension is much too soft.

Here at Milner’s we developed a kit to abolish the NP300’s flaws / poor rear suspension characteristics.

The Milner kit will restore the vehicle to a more usable ride height when loaded/towing without compromising comfort when empty.

Kit Comprises of:
2 x Upgraded Coil Springs
2 x Heavy Duty Shock Absorbers

(The shock absorbers must be used to overcome the effects of the stronger spring.)

How Often Should I Change My Gearbox Filter And Oil?

HOW OFTEN SHOULD I CHANGE MY GEARBOX FILTER

How Often Should I Change My Gearbox Filter And Oil?

Why Do I Have A Gearbox Filter?

Well as you rack up more miles in your vehicle, the auto gearbox is working very hard under the heat from your daily journeys. Your gearbox oil may become contaminated with worn bits of the internal gears. If these impurities are not drained out, they will shorten the life of your gearbox.
To prevent this from happening you should change your gearbox filter regularly, as this is your savior keeping you from expensive gearbox problems.
The filter removes the impurities floating around within the oil, whilst the oil not only acts as a lubricant but also as a coolant.

How Often Should I Change My Gearbox Oil And Filter?

Milner’s number one technical guy advises, personally he likes to change ALL the oils and filters when he purchases a new vehicle. Not only because it gives him peace of mind, but how can you really be sure when they were last done?

Below are ‘typical’ suggestions on changes.

Automatic:  The typical service interval is 60,000 to 100,000 miles. However Milner’s would recommend that you change annually, just like you would with your engine oil and filters.

Manual: Many manufacturers recommend that manual transmission fluid be changed every 30,000 to 60,000 miles. Although if you check your owners manual, it will advise your vehicles recommendation.

Typically the colour of the fluid could indicate you that it requires changing.
If you do a lot of driving under high-stress conditions, you should check the transmission level more often and have a garage check the condition of the fluid. Transmission fluid often is red but can come in other colors, and as it deteriorates it tends to turn darker and sometimes smells burnt.

 

How Easy Is It To Change My Gearbox Oil And Filter?

When asking the question to one of our Milner Race engineers, he quickly replied with ”An absolute nightmare!” However he quickly retracted that statement and said it depends what vehicle it is on.

If you are fortunate to have a drain plug on your sump pan, it should be relatively easy and mess free. However if you are less fortunate – you will most definitely need a catch pan that is wider than your gearbox assembly.

Simple Steps To Changing Gearbox Fluid And Gasket:

  1. Place catch pan under drain whole or under the gearbox assembly.
  2. Unscrew drain bolt or remove gearbox pan, to start drainage.
  3. Remove the old gasket and filter.
  4. Inspect the gearbox pan. Make sure that the magnet (inside the casing) is clear of any small metal shavings, any large shavings may indicate more serious gear wear.
  5. Fit the new filter and gasket and bolt the pan back onto the vehicle.
  6. Ensure you have the correct replacement fluid, this can be found in your owners manual under their recommendations. Also check the amount that your vehicle requires.
  7. Pour in the correct amount of fluid.
  8. Start your vehicle and let it run for a few minutes and check the fluid level.
  9. Dispose of your used fluid correctly. Here is a handy link: http://www.oilbankline.org.uk/

So when you are giving your vehicle a service, don’t forget to change the gearbox oil and filter as well.

Vehicle Recall Checker – Is Your 4×4 Being Recalled?

vehicle recall checker

Sometimes when a car is released to the world, something can go overlooked and major problems can arise.

In the event of this happening, a recall usually happens, meaning that the driver has to send their car back to the manufacturer for work.

This has been in the news a fair amount over the last few years, with millions of cars recalled for everything from faulty airbags to electrics causing fires.

If your car has been recalled, it is extremely important to ensure that you return it swiftly so that the work can be done. So, there is a Government recall checker tool that allows users to quickly and easily see if their vehicle is part of an outstanding safety recall simply by entering a few details about their vehicle..

Many drivers are friends and fans of Milner Off Road thanks to the wide range of 4×4 parts that we supply, and therefore we want to ensure that everyone keeps their vehicle running as safely and smoothly as possible.
